Merge #13180: Fix re-declared scoped enum as unscoped (Causes issues with some compilers)

43f3dec Remove enum specifier (to avoid re-declare scoped enum as unscoped) (donaloconnor)

Pull request description:

  MSVC fails to compile with the changes made in #10742

  The problem is enum types were changed to scoped (`enum class`) but in some places `enum` as an unscoped is used.

  This is a very simple fix and I've tested it.

  Edit: Had to remove enum altogether - `enum class` doesn't compile on clang.
